chore: migrate from eslint to oxlint

[B4nan]

Summary

Replaces ESLint with oxlint, pulling in the shared @apify/oxlint-config preset and oxlint-tsgolint for type-aware rules. Mirrors the migration already shipped in apify-storage-local-js, apify-shared-js, apify-client-js, and apify-core. Biome stays as the formatter — no formatting changes.

What changed

• Drop @apify/eslint-config, eslint, eslint-config-prettier, eslint-plugin-react, eslint-plugin-react-hooks, globals, typescript-eslint
• Add oxlint@1.62.0, oxlint-tsgolint@0.22.0, @apify/oxlint-config@^0.2.5
• Bump @apify/tsconfig to ^0.1.2 (drops removed importsNotUsedAsValues option that oxlint-tsgolint flags as invalid)
• Replace eslint.config.mjs with oxlint.config.ts; drop unused tsconfig.eslint.json
• lint / lint:fix (and lint-staged) now run oxlint --type-aware
• Drop the dangling references: [{ "path": ".." }] from test/tsconfig.json — the root tsconfig isn't a composite project, and tsgolint rejects the malformed reference. The reference wasn't doing anything for tsc either.
• Auto-fix surfaced one regex that should use String#startsWith (utils.ts).

Things to note

• website/ (one .jsx file) is ignored, matching biome's behaviour. Not worth carrying React linting just for that.
• The no-restricted-syntax rule that forbade direct LoginCommand calls in tests is gone — oxlint doesn't implement that rule yet. Convention now relies on review + the safeLogin() helper in test/__setup__/hooks/useAuthSetup.ts. Could be re-added as a custom oxlint plugin (like apify-core's oxlint_plugins/local.mjs) if desired.

Lint output

$ pnpm lint
Found 0 warnings and 0 errors.
Finished in 466ms on 244 files with 117 rules using 14 threads.

Test plan

• pnpm lint — clean
• pnpm format — clean (still on biome + prettier for markdown)
• pnpm build — TypeScript + tsdown both succeed
